This NASA Hubble Space Telescope image shows the diverse collection of galaxies in a galaxy cluster called Abell S0740, located more than 450 million light-years away in the direction of the constellation Centaurus.
A gap exists between scientific knowledge of vitamins and how they are popularly used. Translating emerging science to better policy will require a regulatory framework that addresses the content and labeling of vitamins and the effects on nutrient adequacy and chronic degenerative disease prevention.
The federal Conservation Security Program rewards farmers for land stewardship, yet many New England farmers were not eligible to participate. A report demonstrates how farmers would benefit from increased CSP effectiveness through funding allocations, administrative adjustments, and statutory change.
Working in the remote forests of Cambodia, conservationists from the Wildlife Conservation Society (WCS) have just discovered Southeast Asia's only known breeding colony of slender-billed vultures, one of the world's most threatened bird species.
A toxin derived from a reclusive sea creature resembling a translucent doughnut has inspired UT Southwestern Medical Center researchers to develop a related compound that shows promise as a cancer treatment.
A year after the National Weather Service implemented a new rating scale to more accurately measure tornado intensity, Texas Tech University wind researchers are in tornado-ravaged portions of Florida this week to study how well the new scale worked.
"Editors' Choice" in the current issue of Science magazine, tags them, "Singing Vents." Long assumed to be silent, fluids in black smoker hydrothermal vents not only generate rumbling sounds but, as an added surprise, they produce resonant tones. Listen to what University of Washington scientists have recorded nearly a mile and a half below the surface.
A University of Arkansas researcher and her colleagues are developing a way to examine how the genomes rearrange themselves during hybridization to better pinpoint how genetically modified organisms may behave when they cross with naturally occurring plants.
Modest changes in the 1918 flu virus's hemagglutinin receptor binding site"”a molecular structure critical for the spread of infection"”stopped viral transmission in ferrets, according to a new study conducted by researchers at Mount Sinai School of Medicine and at the Centers for Disease Control and Prevention.
Today, National Science Foundation (NSF) Director Arden L. Bement, Jr., proposed an investment of $6.43 billion in fiscal year (FY) 2008 for agency programs to advance frontiers of research and education in science and engineering. The request includes an increase of nearly $409 million over the FY 2007 request of $6.02 billion.
A greenhouse gas that has become the bane of modern society may have saved Earth from completely freezing over early in the planet's history, according to the first detailed laboratory analysis of the world's oldest sedimentary rocks.
Wind researchers from Texas Tech University are in Florida this week to study debris and damage from tornados that killed 20 people Friday. Their work could lead to changes in construction standards and guidelines that could better safeguard families during wind events.
Zdzisław Pawlak (1926-2006) was a pioneer in the field of knowledge description systems and rough sets during the 1970s and 1980s. New Frontiers in Scientific Discovery - Commemorating the Life and Work of Zdzisław Pawlak, published by IOS Press, is dedicated to the memory of Zdzisław Pawlak, a great scientist and a great human being.
A Georgia Tech physics group has discovered how and why the electrical conductance of metal nanowires changes as their length varies. Determining the structural properties of nanowires is a big challenge facing the future of nanotechnology.
Gerome A. Miklau, assistant professor of computer science at the University of Massachusetts Amherst, has received a five-year, $500,000 federal grant to study privacy and accountability in computer database systems.
Researchers at the University of Delaware have received a $960,000 grant from the U.S. Department of Energy (DOE) to identify low-cost, nano-sized catalysts"”tiny amounts of metal compounds"”that can spur the chemical conversion of liquid fuels into hydrogen for powering cars to heating homes.
Researchers at Purdue University have shown how to create a new class of tiny sensors for applications ranging from environmental protection to pharmaceutical preservation.
This is an editorial from a veterinarian, director of a comparative medicine facility at a major institution, addressing the link between Barbaro's treatment and animal research.
Using a series of interactive computer programs that focus on the mathematics embedded in various cultural designs, students from across the country in grades 4-12 have shown a statistically significant increase in their math achievement scores. Now a new NSF grant will help the Rensselaer researcher who developed these programs extend their use to help engage underrepresented minority students in the subject of computing.
Peering backward in time to an instant after the big bang, physicists at the University of Wisconsin-Madison have devised an approach that may help unlock the hidden shapes of alternate dimensions of the universe.
